  • Patent number: 8386066
    Abstract: The invention relates to a method for suppressing the influence of roll eccentricities on the run-out thickness of a rolled stock, which runs through a rolling stand, roll eccentricities being identified by using a process model and taken into consideration in the determination of a correction signal for at least one final control element, preferably a final control element for the adjustment position, of the rolling stand, wherein the measured tensile force upstream of the rolling stand is fed to the process model to identify the roll eccentricities. According to the invention, variations in tensile force are fed back in a targeted manner to reduce the effects of periodic roll eccentricities on the rolled stock, whereas all other sources of variation are eliminated. A process model of the rolling nip and the rolls, preferably based on the observer principle, produces reliable data on the roll eccentricity.

  • Patent number: 7467533
    Abstract: Method for changing working rolls of a roll stand provided with a roll displacement device located on the first side of the stand moving a roll along a loading axis (C, C?). Each has fastening means at a first end towards the first side and matching fastening means at a second end towards the second side of the stand opposite to the first side. Matching fastening means are on the displacement device. The substitute roll can be placed on either side of the stand. The displacement device operates by pulling when the substitute roll is on the second side simultaneously extracting the roll to be replaced towards the first side and loading the substitute roll from the second side; and, vice versa, by pushing when the substitute roll is on the first side of the stand. The various fastening means and matching fastening means are respectively coupled and decoupled.

  • Patent number: 7191629
    Abstract: A modular rolling mill comprises a plurality of separate rolling units arranged along a mill pass line. Each rolling unit includes at least two pairs of work rolls defining oval and round roll passes and carried on roll shafts that are staggered 90° with respect to each other. The rolling units contain intermediate drive trains configured to connect the roll shafts to parallel input shafts projecting to a first side of the pass line from the respective rolling units. A single driven line shaft is parallel to and on the first side of the pass line. Output shafts are mechanically coupled to the line shaft by bevel gear sets. The output shafts project laterally from the line shaft towards the pass line and are connected by separable couplings to the input shafts of the rolling units.

  • Patent number: 7165432
    Abstract: A device for changing pairs of work rolls and/or pairs of backup rolls of roll stands, wherein the rolls are each supported in chocks and are movable out or in by a lower back up roll supported on a track and wheels. The work rolls on the drive side of the roll stand can be coupled to a hydraulic piston-cylinder actuator that is dimensioned in is stroke length for the removal or installation distance and can be uncoupled when it has been withdrawn by the required distance. A roll changing frame can be coupled to the actuator and, when the upper backup roll and the roll changing frame are supported on the lower backup roll, the pair of backup rolls can be moved out or back in. The actuator is coupled to a pusher with connecting arms aligned with ends of the rolls. The actuator is arranged on the drive side of the roll stand and is coupled to the pusher through a piston rod.
